@AndrewMason Received mine, and it sounds great!! Now, as important as good sound is the importance in integrating it to my system. I'd like to hear your view on using one of the SE outputs as "line out" The bridged output are not useful for my setup, I do need volume control for my powered speakers. I do know it's not designed for this, but in gain level 2, unity, when plugged into the very high impedance of a line in, is it correct to assume that a 2V Dac output would still be line level, that there would not be "double amping" since very high impedance line in means no power means no current? Basically, if I do connect one of the 2 SE headphones output to my powered speakers, am i doing something wrong in term of sound quality?

Hi Pierre. The TRS SE outputs aren't fixed 2 V out... they're variable according to gain knob and vol control. If you use 2V DAC and set gain knob to "2" (0dB) then you'll have 0-2 V rms output from the TRS. And I strongly recommend using TRS cables with low impedance ground to minimize hum pickup in an unbalanced setup like that e.g. Monoprice 5576.

Thanks Andrew, yes of course it wouldn't be a fixed output, This is the Idea of having a volume control, but what I meanth was should I expect a normal behavior and no degrradation of sound quality when Using an amped output to plug in a line in or is it really better to use the SE Pass output and find something else to rely on for volume control. And if I do am I correct to use the gain setting #2 for that task. To my knowledge 0-2V is a proper preamp output, and in the case of a line in it has very high impedance so no current/no power. So basically the question is does the SE output "behave" like a line out when connected in a line in or does it create problems that I don't see/understand properly

Hi Pierre. Yes using the 789 TRS outputs (gain 2) as a preamp output will be super clean, low THD+N, and low impedance. To minimize ground hum pickup, use low-ground-impedance TRS cables throughout and plug all your audio devices into the same power strip. Assuming your powered monitors are 0-2V compatible, then I don't foresee any other problems.
